ABSTRACT:
A semiconductor memory device according to the present invention comprise a plurality of arrays each supplied with a common column address signal. In an selected array, the potential of a data line is set to a potential corresponding to a potential supplied to a corresponding bit line in response to the potential of the bit line, the potential of the corresponding column address signal and the potential of a terminal. In non-selected array other than the selected array at this time, since the potential of a terminal in the non-selected array is set to a potential different from that of the terminal in the selected array, the potential of the data line remains unchanged irrespective of the column address signal.
